I have a Sony x940d and I'm having the same issue. However, the 4k broadcast on 1080p looks significantly better than 1080p. Does that mean the picture is in 4k regardless of the aspect ratio setting?
Telus support just told me they have not ETA for the firmware fix. Really annoying as this was the only reason I switched from Shaw.
I'm in the same boat. I bought a 4K Sony TV and had Telus install 4K Fibre Optic at my house. My plan was to watch the Olympics in 4 K. So that turned out bad. Seems like a case of over promising and under delivering.
i just called Telus for a date for the fix. They said it would be sometime this Fall. As far as I'm concerned "in a couple of weeks" and "sometime this Fall" is not the same thing.
This information should have been made known before I signed on with Telus.
